Key Features
Compact design
Thanks to the right-angled axis offset design, worm gears can be integrated into machines and systems in a particularly space-saving manner – ideal for confined installation situations.
Quiet and quiet running
The sliding friction between the worm and worm wheel ensures low-vibration, particularly quiet operation – perfect for noise-sensitive environments.
High reduction ratios in one stage
With ratios of up to 8000:1 (and more), high torque outputs can be achieved without complex multi-stage solutions.
Self-locking
Many worm gears offer a natural holding function. This prevents unintentional reversal – e.g. when carrying loads on inclines or when swivelling movements.
Versatile installation positions
Worm gearboxes can be mounted in almost all positions – horizontal, vertical or inclined – and thus offer maximum flexibility in the machine layout.
Low-maintenance due to permanent lubrication
Thanks to their closed design and lifelong grease filling, they are particularly easy to maintain and durable in operation.
Optionally with IP65 protection
For use in damp, dusty or cleaning-intensive environments, models with a high degree of protection are available.
Can be combined with different engine types
Whether standard motor, EC motor or integrated converter (e.g. SmartLine) – our worm gears have a modular design and can be flexibly combined.
Variety of variants & special solutions
Thanks to our vertical range of manufacture, individual adaptations in flange, shaft, colour or transmission are possible – even from small quantities.
Wide selection of electric motors available for immediate delivery.

The advantages of worm gearboxes from rührgetriebe
Our worm gear units feature closed and robust housings that provide maximum stability when mounted and are suitable for both directions of rotation.
The steel worms are hardened and ground, while the worm wheels are made of high-quality special bronze with excellent sliding properties. By using synthetic gear grease or oil (with NSF H1 approval), you benefit from low noise emission and a long gearbox lifespan. Each gearbox is equipped with ball bearings, ensuring above-average longevity even in continuous operation and various installation positions.
Based on our many years of experience, we have preconfigured the most common modular systems for you. This provides you with a technically and economically mature solution in every respect for the majority of applications.
